2016/11/21 - Amazon EC2 Container Service - 8 updated api methods
Changes Update ecs client to latest version
{'containerInstance': {'version': 'long'}}
Deregisters an Amazon ECS container instance from the specified cluster. This instance is no longer available to run tasks.
If you intend to use the container instance for some other purpose after deregistration, you should stop all of the tasks running on the container instance before deregistration to avoid any orphaned tasks from consuming resources.
Deregistering a container instance removes the instance from a cluster, but it does not terminate the EC2 instance; if you are finished using the instance, be sure to terminate it in the Amazon EC2 console to stop billing.
Request Syntax
client.deregister_container_instance(
cluster='string',
containerInstance='string',
force=True|False
)
string
The short name or full Amazon Resource Name (ARN) of the cluster that hosts the container instance to deregister. If you do not specify a cluster, the default cluster is assumed.
string
[REQUIRED]
The container instance ID or full Amazon Resource Name (ARN) of the container instance to deregister. The ARN contains the arn:aws:ecs namespace, followed by the region of the container instance, the AWS account ID of the container instance owner, the container-instance namespace, and then the container instance ID. For example, ``arn:aws:ecs:region:aws_account_id:container-instance/container_instance_ID ``.
boolean
Forces the deregistration of the container instance. If you have tasks running on the container instance when you deregister it with the force option, these tasks remain running until you terminate the instance or the tasks stop through some other means, but they are orphaned (no longer monitored or accounted for by Amazon ECS). If an orphaned task on your container instance is part of an Amazon ECS service, then the service scheduler starts another copy of that task, on a different container instance if possible.
Any containers in orphaned service tasks that are registered with a Classic load balancer or an Application load balancer target group are deregistered, and they will begin connection draining according to the settings on the load balancer or target group.

An optional tag specified when a task is started. For example if you automatically trigger a task to run a batch process job, you could apply a unique identifier for that job to your task with the startedBy parameter. You can then identify which tasks belong to that job by filtering the results of a ListTasks call with the startedBy value. Up to 36 letters (uppercase and lowercase), numbers, hyphens, and underscores are allowed.
If a task is started by an Amazon ECS service, then the startedBy parameter contains the deployment ID of the service that starts it.

Stops a running task.
When StopTask is called on a task, the equivalent of docker stop is issued to the containers running in the task. This results in a SIGTERM and a 30-second timeout, after which SIGKILL is sent and the containers are forcibly stopped. If the container handles the SIGTERM gracefully and exits within 30 seconds from receiving it, no SIGKILL is sent.

Updates the Amazon ECS container agent on a specified container instance. Updating the Amazon ECS container agent does not interrupt running tasks or services on the container instance. The process for updating the agent differs depending on whether your container instance was launched with the Amazon ECS-optimized AMI or another operating system.
UpdateContainerAgent requires the Amazon ECS-optimized AMI or Amazon Linux with the ecs-init service installed and running. For help updating the Amazon ECS container agent on other operating systems, see Manually Updating the Amazon ECS Container Agent in the Amazon EC2 Container Service Developer Guide.
